T 0 all whom it may concern:

Be it known that I, EDWARD Boon, a subject ofthe King of Great Britain and Ireland, and a resident of Middleton Junction, in the county of Lancaster, England, have invented a certain new or Improved Apparatus for Pressing Cop and like Tubes upon Spindles, of which the followingis a specification.

These improvements relate to apparatus for use in pressing tubes uponspindles in textile machinery, which tubes may be of paper or fibre, and. have for object improvements in or modifications of the apparatus described and claimed in my prior application No. 483822, filed July 11, 1921, now Patent f -1,435,450, dated Nov. 14, 1922. In the said patent I have described an 'apparatus in which two plates are used, provided with holes to grip the tubes, with means for drawing; the plates apart or forcing them together. The plates when forced together gripped the tubes in the holes of the apparatus and the said tubes were thus easily and securely pressed down upon the spindles, thus obviating the pressure of the tubes upon the spindles by hand, with the consequent irregularity of pressure, slowness of operation and destruction of the frail tubes.

I find that whilst the apparatus so described and claimed in the specification accompanying my prior patent above referred to works excellently in practice, the fact that each of the separate plates has a handle which projects from the outer face of the plate and centrally thereof is an inconvenience when the apparatus is used in connection with the spindles of ring spinning frames, and the object of these present improvements is an apparatus which may be employed such ring spinning frames or in any case where space around the spindles is limited.

In carrying the said improvements into effect I provide the two plates as before to grip the tubes, but the handles are placed on one side of the apparatus, being fitted on spindles passing through the plates and secured to one of them, whilst the other plate is moved to and from the said plate to which the spindles are fixed by angular motion of the handles which, by means of a quick screw on the spindles, press the movable plate against the other, or draw it therefrom.

The improvements will now be fully de- 1922. Serial No. 557,940.

scribed with reference to the accompanying drawings, wherein.

Fig. 1, is a top plan of the apparatus with:

the handles removed. v

, Fig. 2, isa frontelevation of Fig. 1.

Fig.3, is a complete plan of the apparatus, and

. F ig. 4, a horizontal section showing the apparatus to an enlarged scale.

Referring tothe drawings generally, a and b are the two plates of the prior patent above referred to preferably of aluminium although theyv may be of other material-. and c are the holes to receive the tubes, the holes being formed of suitable centre .pitCh to suit the distance between the spindles of the machine with which the apparatus is to be used. The holes are as before flared at their lower ends (Z for the easy and accurate entry of the tubestherein as the apparatus is placed upon them to press the tubes upon the spindles. 6 and f are spindles secured to the plate Z) preferably in the manner clearly shown in Fig. 4:, having a threaded shank engaging in the tapped hole in the plate asshown and secured by the nuts 9. A locknut may be provided with each fastening nut. Each spindle e, f has formed or rolled upon it the thread it adapted to engage with a thread formed on the inner face of a sleeve or handle 2', the latter being recessed as shown to allow for the movement of the handle longitudinally of the spindles e, f by reason ofthe screw engagement between them, when the handle 2' is angularly moved. One extremity of each spindle proper passes through a hole in the plate 5, and this hole may be countersunkon its outer edge, as shown at j.

In each plate a and b, are formed recesses it these recesses being in such a position that a recess is in one plate registers with a corresponding recess in the other plate. They are preferably formed in the position shown in Fig. 3. Within each pair of corresponding recesses is placed a spring Z.

In practice, when it is desired to press the tubes down upon the Spindlesin the spinning or other machine. the plates at and b are separated by the operative taking the apparatus by the handles 2' and giving each handle a turn inwards towards the centre, that is, the handle to the left of Fig. will turn clockwise and the handle to the right counterclockwise The handles therefore more along thespindles towards their outerext-remities, by reason ofthe left dles e, f, and the spring Zthen force the two plates a and Z) apart. The apparatus may then be placed over the spindles of the machine to press the tubes thereupon, and by giving each handle a turn in the contrary direction to the opening movement, plate I) is pushed against plate a enclosing the tubes in the holes 0 and allowing for the pressing of said tubes upon the spindles of the machine.

Stops m may be fitted to each spindle, the

ends of said stops projecting into the countersunk recesses n in the handles 2' may be provided on each handle to limit the angular motion of thesaid handles in the opening movement of the plates. y

Y The handles 2' may be milled as shown or finished in any other suitable manner. Also the apparatus may be constructed to press any een venient number of tubes, the five tube holes 0' shown in the figures being merely by way of example.

Q If desired, washers of brass or other metal alloy may be fitted in any convenient manner between the plate B and the handles 2' to take the pressure of the said handles on the latter upon spindles in textile machinery, two

plates arranged parallel to each other corresponding recesses formed in each plate to grip the tubes, two spindles fitted to one plate and assing through the other plate and rotatable sleeves mounted upon the spindles, and in screwed engagement therewith sprin s between the plates to force same apart and stops upon the spindlesto limit the angular movement which may be given to the sleeves mounted thereon.

In testimony whereof I have hereunto set my hand.

' EDWARD BUCK.
